在第一方面的一种实现方式中，结构层具有相对的第一面和第二面，第一面连接功能部件，第二面连接第二壳体。第一面与功能部件的结合力小于第二面与第二壳体的结合力。当拆卸第二壳体对电子设备进行维修时，此方案可以便于结构层与功能部件分离，而结构层仍然与第二壳体粘接，使得整个结构层连同第二壳体一并被拆卸下来。结构层两侧设置强弱连接方式的好处在于，在拆卸作业中，功能部件不易被拉扯、损坏，也不易残留余胶，这不仅减小了拆卸难度，还有利于保证功能部件的寿命与可靠性。
在第一方面的一种实现方式中，结构层包括连接层，连接层的材料为连接材料。第一面为连接层的表面。连接材料由于其材料特性，连接力较弱，因此适合将连接层设于结构层靠近功能部件的一侧，依靠连接材料的特性，实现第一面与功能部件结合力较弱的需求。

具体实施方式
本申请以下实施例提供了一种电子设备，该电子设备包括但不限于手机、平板电脑、笔记本电脑、电子阅读器、大屏设备、音箱、移动Wi-Fi、可穿戴设备(例如智能手表)等。下文将要描述的该电子设备可以是手机。
如图1所示，电子设备10可以包括中框1、显示屏6、扬声器模组3、电池4、结构层5和后壳2。
其中，中框1作为电子设备10的主要结构承载件，用于承载上述除中框1之外的其他部件。显示屏6可以安装在中框1的一侧，扬声器模组3、电池4和结构层5可以安装在中框1的另一侧。后壳2盖合在中框1上，并位于中框1背离显示屏6的一侧。显示屏6、中框1和后壳2可以安装围成安装腔10a，扬声器模组3、电池4和结构层5均位于安装腔10a内。如图1所示，中框1的侧壁可形成整机出音孔1a，整机出音孔1a贯通该侧壁。在其他实施例中，整机出音孔也可以开设在后壳上。
中框1与后壳2的具体结构可以根据产品需要设计，本实施例不做限定。中框1与后壳2均属于电子设备的壳体，为了区分，可以将中框1称为第一壳体，将后壳2称为第二壳体。
图1所示的电子设备10可以是不能折叠的直板手机，可以理解的，这仅仅是一种举例。实际上，本申请实施例的电子设备还可以是可折叠手机。或者，本申请实施例的电子设备可以是没有显示屏的电子产品。本实施例中，电池4属于一种功能部件。功能部件指安装在安装腔10a中的除扬声器模组3以外的部件。功能部件可以具有一定机械功能(包括但不限于支撑、限位、收容、连接、配合)、电气功能(包括但不限于电连接、充放电、信号辐射、电磁屏蔽、信号处理、滤波、图像采集、指纹信息采集、音频采集)， 和/或其他功能(如散热等热力学功能)。除电池4以外，功能部件例如还可以包括摄像头模组、指纹模组、振动马达、天线辐射体、屏蔽罩/屏蔽框、电路板等。下文将针对电池4这个功能部件继续描述，但实际上下文所述适用于任意的功能部件。
如图1、图2、图3和图4所示，扬声器模组3可以与电池4相邻。扬声器模组3可以包括模组壳体和扬声器单元33。模组壳体可以包括第一模组壳体31、第二模组壳体32和前腔盖板34。第一模组壳体31与第二模组壳体32包围形成收容腔3c，第一模组壳体31具有安装通孔31a与模组出音孔3d，模组出音孔3d与电子设备的整机出音孔1a对准，安装通孔31a与收容腔3c连通，前腔盖板34封盖安装通孔31a。扬声器单元33安装在收容腔3c内，并将收容腔3c分隔为前音腔3a和后音腔3b两个腔体。其中，前音腔3a由第一模组壳体31、前腔盖板34和扬声器单元33围成，前音腔3a与安装通孔31a和模组出音孔3d连通。后音腔3b由第二模组壳体32和扬声器单元33围成，扬声器模组3的后音腔3b与电子设备10的安装腔10a连通。扬声器单元33包括振膜，扬声器单元33用于实现电声转换以发出声音。扬声器单元33产生的声波通过前音腔3a、模组出音孔3d和整机出音孔1a传播到电子设备10外部，以被人耳接收形成听觉。此种开放式后音腔3b设计将安装腔扩展为扬声器模组3的后音腔3b，能够实现大音量、立体声等音效，增强扬声器模组3的音质表现。可以根据产品需要设计扬声器模组3的具体结构，本申请实施例中对此不做限定。
由于电子设备10的扬声器模组3具有开放后腔设计，在扬声器模组3工作时，声波造成的强气流会冲击后壳2，用户触摸后壳2时能明显感受到壳振，长时间使用可能会导致用户手麻，影响用户外放音乐及外放通话等场景下的手持体验。
本申请实施例提供的电子设备10可以从两个方面减轻或抑制电子设备10的振动，两方面的减振设计相对独立，也可以组合使用。接下来将详细描述。
一方面，可以从抑制振动源(即上文提到的扬声器模组3)和振动体(包括上文提到的后壳2)振动的角度改善振动问题。
如图4所示，示意性的，扬声器模组3的前腔盖板34可以采用阻尼材料制成，该阻尼材料例如可以是阻尼硅胶或者阻尼合金等。对于阻尼合金，例如可以是高锰基阻尼合金、Mg系阻尼合金、Mn-Cu阻尼合金(或称Mn系阻尼合金)等。该阻尼材料具有阻尼性能，能够消耗机械振动能。当声波造成的气流在前音腔3a内流动时，会冲击由阻尼材料制成的前腔盖板34，由于阻尼材料的阻尼特性，前腔盖板34可以耗散冲击能量，从而减轻扬声器模组3的振动。
如图3所示，示意性的，可以通过连接件35将扬声器模组3与中框1固定。连接件35可以为阻尼材料制成的紧固件，阻尼材料例如可以为上述的阻尼硅胶或者阻尼合金。连接件35例如可以是阻尼合金螺钉。当扬声器模组3振动时，连接件35可耗散冲击能量，降低扬声器模组3的振动。
示意性的，如图1所示，后壳2靠近安装腔10a的一侧可以具有减振部，减振部的结构可以根据需要设计，例如可以为块状、柱状、筋状等。减振部可以用阻尼材料制成，例如上述的阻尼硅胶或者阻尼合金。减振部在受到冲击时能够耗散冲击能量，减少后壳2的振动。
另一方面，可以通过设在后壳2和功能部件之间的结构层5实现减振。在本申请实施方式中，结构层5也可以称为辅料，辅料可以与第二壳体预先组装形成壳体组件。
如图1所示，一种实施方式中，结构层5可以呈片状，结构层5位于电池4与后壳2之间。结构层5具有相对的第一面和第二面，结构层5的第一面与电池4连接，结构层5的第二面与后壳2靠近安装腔10a的内表面连接。结构层5的外形可以按照如下原则进行设计：使结构层5与电池4重叠的面积尽量大，以保证对电池4所在区域的粘接力度。例如，结构层5的外形可以与电池4基本相同，结构层5近似呈矩形片状。结构层5的边界轮廓可以不超出电池4的边界轮廓，例如结构层5的边界完全内缩于电池4的边界之内，此时结构层5可以与电池4近似共中心，结构层5的各边与电池4的各条对应边的间距可以近似相等；或者结构层5的边界与电池4的边界基本重合。在其他实施例中，可以根据产品需要设计结构层5的外形，使结构层5的外形与结构层5所粘接的功能部件匹配，不限于上文所述。
示意性的，结构层5的第一面与电池4的结合力可以较小，结构层5的第二面与后壳2的结合力可以较大。因此，可以将结构层5的第一面称为弱连接侧，将结构层5的第二面称为强连接侧。需要说明的是，本申请所有实施例中的“强”与“弱”的描述仅仅针对结构层5与电池4和结构层5与后壳2的结合力的大小对比，属于二者之间的相对比较，并非为与特定数值相比较下的强弱定义。示意性的，强连接侧的结合力F1的取值范围可以为F1≥1N/cm，弱连接侧的结合力F2的取值范围可以为0.01N/cm≤F2≤1N/cm。
在本申请实施方式中，可以通过磁吸或者粘胶的方式，连接结构层5和电池4以及后壳2。当结构层 5的两侧通过粘接的方式实现连接时，可以使结构层5粘接后壳2的第二面粘性较强，而粘接电池4的第一面粘性较弱。粘接方式简单高效，能够提升产品的可拆卸维护性。当结构层5的两侧通过磁吸实现连接时，可以在电池4和后壳2上设置磁吸膜以与结构层5两侧磁吸，其中，结构层5可以自带磁性，或者结构层5可以贴附磁吸膜。
当拆卸后壳2对电子设备进行维修时，此种设计可以便于弱连接侧与电池4分离，而强连接侧仍然与后壳2粘接，使得整个结构层5连同后壳2一并被拆卸下来。结构层5两侧设置强弱连接方式的好处在于，在拆卸作业中，电池4不易被拉扯、损坏，也不易残留余胶，这不仅减小了拆卸难度，还有利于保证电池4的寿命与可靠性。
结构层5可以至少包括能量耗散结构、弹性缓冲结构和反向约束力结构这三种结构中的一种，也即结构层5可以包括上述三种结构中的任意一种、任意两种，或者全部。下面分别进行说明。
弹性缓冲结构的材料为弹性材料，该弹性材料包括但不限于硅胶、泡棉或者泡沫胶等。弹性缓冲结构具有弹性形变性能，可以依靠其自身的弹性性能和冲击压缩率可以用来缓冲瞬态冲击，为后壳2提供压缩反弹力，该压缩反弹力可以作为结构层5向后壳2施加的预紧力，起到抑制后壳2振动的作用。同时，弹性缓冲结构的弹性形变特性能够适配电池4与后壳2的间隙公差，保证电池4与后壳2的可靠组装。
示意性的，弹性缓冲结构的压缩反弹力的取值范围可以在5kpa-50kpa之间，该压缩反弹力大小适中，可以防止因为弹性缓冲结构在后壳2和电池4之间伸展顶起后壳2使得壳体开胶失效。
能量耗散结构可以采用阻尼材料构成，因此能量耗散结构也可以称为阻尼结构。构成阻尼结构的阻尼材料例如可以是阻尼硅胶或者阻尼合金等。对于阻尼合金，例如可以是高锰基阻尼合金、Mg系阻尼合金、Mn-Cu阻尼合金(或称Mn系阻尼合金)等。阻尼材料由于自身的特性，可以将固体机械振动能转变为热能而耗散，因此阻尼材料可以用来吸收并且消耗瞬态冲击带来的能量，从而起到减振的作用。
能量耗散结构可以具有任意合适的结构形态。例如，能量耗散结构可以是由阻尼材料制成的阻尼弹性件。阻尼弹性件自身可弹性形变。阻尼弹性件例如可以是微弹簧结构，微弹簧不仅具有阻尼材料的性能可以起到耗散能量的作用，微弹簧的机械结构在受到冲击时也会发生弹性伸缩形变。
反向约束力结构可以由连接材料构成，连接材料具有连接作用，其例如可以为粘性材料或者磁性材料。反向约束力结构可以在后壳2振动的过程中，向后壳2提供反向的约束力。当反向约束力结构由粘胶构成时，粘胶提供的粘性力即为反向约束力；当反向约束力结构由磁性材料构成时，例如磁吸膜等弱磁性材料，磁性材料提供的弱磁力即为反向约束力。当后壳2振动时，后壳2会离开平衡位置运动起振。结合图1，当后壳2向远离或者靠近电池4的方向运动时，反向约束力结构均会提供与后壳2运动方向相反的反向约束力以抑制后壳2振动。
上文说明了用于构成结构层5的三种组分。在一种实施方式中，三者中的任意一种结构均可以单独构成结构层，从而实现减振的功能。在其他实施方式中，三种结构也可以相互配合以实现减振功能。例如可以任选两种结构以构成结构层，也可以使三种结构共同参与构成结构层5。任选一种或两种结构构成结构层5的方式可以根据需要任意搭配设计，本文不做过多的展开描述，下文将描述三种结构共同组合构成结构层5的实施方式。
在一些实施方式中，弹性缓冲结构、能量耗散结构和反向约束力结构可以为三层各自独立的结构，三者层叠连接构成结构层5，层叠的顺序可以根据需要任意设置。相邻层结构之间固定连接，例如可以是粘结。其中，弹性缓冲结构52和能量耗散结构53的厚度取值范围均可以在0.1mm-1mm之间，反向约束力结构51的厚度取值范围可以在0.5mm-1mm之间。
如图1和图5所示，在一种实施方式中，能量耗散结构53形成阻尼层，弹性缓冲结构52形成弹性层，反向约束力结构51形成连接层，可以将弹性层和连接层构成的结构称为第一层。在本实施方式中，第一层与阻尼层层叠设置。其中，反向约束力结构51(图5中方向朝向左下的阴影线填充结构代表反向约束力结构51，且后文所有实施方式均以此填充结构表示)可以靠近电池4，反向约束力结构51与电池4连接，反向约束力结构51与电池4连接的表面为第一面。弹性缓冲结构52(图5中方向朝向右下的阴影线填充结构代表弹性缓冲结构52，且后文所有实施方式均以此填充结构表示)与反向约束力结构51层叠贴合设置。能量耗散结构53(图5中点阵填充结构代表能量耗散结构53，且后文大部分实施方式均以此填充结构表示)的一侧与弹性缓冲结构52贴合，能量耗散结构53的另一侧与后壳2连接。能量耗散结构53与后壳2连接的表面为第二面。
在其他实施方式中，也可以任意调换结构层5的叠层顺序，例如可以使得弹性缓冲结构52靠近后壳2，不仅限于上述例举的实施方式。在其他实施方式中，该第一层可以仅包括该弹性层或者该连接层。
如图1和图6所示，在一种实施方式中，与上述实施方式相似，本实施方式的结构层5同样包括层叠设置的弹性层、连接层和阻尼结构，弹性缓冲结构52形成弹性层，反向约束力结构51形成连接层，能量耗散结构53形成阻尼结构。与上述实施方式不同的是，阻尼结构可以包括多个阻尼弹性件，阻尼弹性件例如可以是由阻尼合金制成的微弹簧的结构，微弹簧的高度可以是0.1mm-1mm，微弹簧支撑于反向约束力结构51与弹性缓冲结构52之间。弹性层与连接层中的一个连接电池4，弹性层与连接层中的另一个连接后壳2。例如可以是反向约束力结构51可以靠近电池4，其与电池4连接的面为第一面。弹性缓冲结构52连接后壳2，其与后壳2连接的面为第二面。此种结构层5能够结合阻尼材料和阻尼结构的优点，提高消耗冲击能量的效率。
上文描述了弹性缓冲结构52、能量耗散结构53和反向约束力结构51均为材料层，三个材料层层叠构成结构层5的实施方式。下面将描述弹性缓冲结构52、能量耗散结构53和反向约束力结构51层叠为两层的实施方式。
在一些实施方式中，结构层5可以为两层材料层，弹性缓冲结构52、能量耗散结构53和反向约束力结构51中的任意两个结构分别作为基质层，两个基质层结构层叠连接；另一个结构可以混入基质层中，混合方式可以是：混入其中任意一个基质层中，或者混入两个基质层中。混合的方式例如可以共混(均匀混合，材料相互均匀掺杂)，或者不均匀混合。
在一种实施方式中，如图1、图7和图8所示，混合的方式可以为均匀的共混，例如在图7中，弹性缓冲结构52作为基质层单独成层，能量耗散结构53均匀混入反向约束力结构51中形成复合层，该复合层与弹性缓冲结构52层叠贴合。弹性缓冲结构52可以靠近电池4，其与电池4连接的面为第一面，能量耗散结构53与反向约束力结构51构成的复合层连接后壳2，其与后壳2连接的面为第二面。
或者在图8中，能量耗散结构53作为基质层单独成层，弹性缓冲结构52与反向约束力结构51均匀共混形成复合层，复合层与能量耗散结构53层叠贴合。能量耗散结构53可以靠近电池4，其与电池4连接的面为第一面，弹性缓冲结构52与反向约束力结构51构成的复合层连接后壳2，其与后壳2连接的面为第二面。
在另一种实施方式中，两结构混合的方式可以为：择其一结构作为基质，另一结构作为增强材料，增强材料混入基质中形成复合层。如图9和图10所示，增强材料为能量耗散结构53，能量耗散结构53呈颗粒状。与上述实施方式相比，能量耗散结构53均与其他基质层混合，但是本实施方式中，颗粒型的能量耗散结构53的粒径大于上述实施方式能量耗散结构53的粒径。如图11所示，增强材料为能量耗散结构53，能量耗散结构53呈纤维状结构。纤维状的能量耗散结构53与基质混合。在其他实施方式中，也可以使用不同的共混结构，不仅限于上述例举的实施方式。
在一种实施方式中，可以选用弹性材料或者连接材料中的一种作为基材层，弹性材料或者连接材料中的另一种作为第一材料，第一材料与阻尼材料混合为复合层。如图1和图9所示，例如可以使弹性缓冲结构52为基材层，能量耗散结构53和反向约束力结构51混合形成复合层，混合的方式可以参考上文例举的实施方式。图9所示的实施方式中，能量耗散结构53为颗粒状增强材料分布在反向约束力结构51构成的基质之内，二者混合为复合层。复合层与基材层层叠贴合设置。弹性缓冲结构52可以靠近电池4，其与电池4连接的面为第一面，能量耗散结构53与反向约束力结构51构成的复合层连接后壳2，其与后壳2连接的面为第二面。在其他实施方式中，也可以使得弹性缓冲结构52作为基质，能量耗散结构53作为增强材料，具体可以根据需要灵活设计。
在一种实施方式中，可以使得阻尼材料、弹性材料和连接材料中的任意两种作为基质，剩余一种作为增强材料。如图1和图10所示，反向约束力结构51和弹性缓冲结构52先构成两层基质层，能量耗散结构53作为增强材料与两个基质混合后形成两层复合层。两层复合层层叠设置。弹性缓冲结构52与能量耗散结构53构成的复合层可以靠近电池4，其与电池4连接的面为第一面，能量耗散结构53与反向约束力结构51构成的复合层连接后壳2，其与后壳2连接的面为第二面。
在一种实施方式中，可以选用弹性材料或者连接材料中的一种作为基材层，弹性材料或者连接材料中的另一种作为第一材料，第一材料与阻尼材料混合。如图1和图11所示，例如可以使反向约束力结构51为基材层，能量耗散结构53和弹性缓冲结构52混合作为复合层，混合的方式可以参考上文例举的实施方式，复合层与基材层层叠设置。反向约束力结构51构成的基材层可以靠近电池4，其与电池4连接的面为第一面，能量耗散结构53与弹性缓冲结构52构成的复合层连接后壳2，其与后壳2连接的面为第二面。复合层的基质可以是泡棉基材，增强材料可以是阻尼合金制成的纤维，多个纤维均匀的在泡棉基材中分布，以构成复合层。当外壳振动时，阻尼合金纤维作为能量耗散结构53吸收振动，释放能量，实现阻尼材料 减振；并且阻尼合金纤维处于泡棉基材中吸收振动时会与泡棉基材也发生摩擦，可以实现摩擦减振，从而进一步加强减振效果。
在一种实施方式中，能量耗散结构53和弹性缓冲结构52均为独立的两层结构，二者层叠设置。反向约束力结构51可以为磁性材料，磁性材料可以在能量耗散结构53和弹性缓冲结构52中均匀混合。可以通过分别调节磁性材料在能量耗散结构53和弹性缓冲结构52的浓度来设置结构层5两侧不同的磁力大小，磁性材料浓度大的一侧磁力较强，可以作为强连接侧与后壳2连接，反之磁性材料浓度小的一侧磁力较弱，可以作为弱连接侧与电池4连接。
上文描述了弹性缓冲结构52、能量耗散结构53和反向约束力结构51混合、层叠为两层构成结构层5的实施方式，下面将描述弹性缓冲结构52、能量耗散结构53和反向约束力结构51混合为一层以构成结构层5的实施方式。
在一些实施方式中，弹性缓冲结构52、能量耗散结构53和反向约束力结构51可以混合为一层结构层5。结构层5可以包括阻尼结构和第一材料。可以将弹性材料和连接材料构成的材料称为第一材料。第一材料与阻尼材料相混合，二者共混的方式有多种。在其他实施方式中，该第一材料可以仅包括该弹性材料或者该连接材料。
第一材料仅为连接材料或者弹性材料中的一种时，第一材料与阻尼材料混合在一起构成结构层。下面将详细说明第一材料包括连接材料和弹性材料的情况。
在一种实施方式中，第一材料与阻尼材料混合的方式为：弹性缓冲结构52、能量耗散结构53和反向约束力结构51相互混合构成结构层5，如图12所示。
在另一种实施方式中，第一材料与阻尼材料共混的方式可以为：择其一作为基质，另一材料作为增强材料，如图13和图14所示。图13所示的实施方式中，第一材料由弹性材料和连接材料构成，弹性材料与连接材料混合为第一材料，第一材料作为基质。阻尼材料构成增强颗粒，掺杂颗粒与基质混合，二者构建成结构层5。图14所示的实施方式中，能量耗散结构53作为基质，弹性缓冲结构52和反向约束力结构51分别作为两种增强颗粒，两种增强颗粒均与能量耗散结构53形成混合以构成结构层5。在其他实施方式中，也可以使用不同的混合方式；增强材料的形式也不仅限于上述例举的实施方式，可以根据需要设置不同的增强材料形态。
上文主要例举了部分类型结构层5的结构设计，实际应用中可以不仅限于上述例举的实施方式，可以根据需要任意设计层级结构组合和材料选型。在其他实施方式中，后壳2可以做特殊的凸起结构以对抗剪切阻尼。接下来将继续介绍后壳2的结构。
如图15和图16所示，后壳2的厚度方向上设置凸起，凸起的形状可以根据需要任意设置，例如可以为柱形、网格形、波浪形凸起等。凸起在后壳2设置的区域可以设在电池4在后壳2处的投影区域。结构层5上设置凹槽，该凸起与该凹槽配合，以使后壳2的凸起嵌入结构层5。本实施方式中，设有凸起的后壳2可以与任意设有凹槽结构的结构层5相配合，示意性的，图15与图16中的结构层5可以是上述任一实施方式中的结构层5。
如图15与图16所示，本实施方式的结构层5与后壳2配合，不仅可以提供对抗电子设备的厚度方向上的压缩变形的阻尼，还可以提供对抗电子设备的左右方向上的剪切变形的阻尼。当电子设备存在沿着图15所示的左右方向振动时，后壳2的凸起与结构层5的凹槽的配合可以消耗左右方向的振动能量。
在电子设备的组装过程中，可将结构层5的强连接侧预先粘贴至后壳2，再将该后壳2组件与电子设备的中框装配，使结构层5的弱连接侧与电池4连接。
由于通过结构层5将后壳2与电池4连接为一体，增大了后壳2的等效质量与刚性，改变了后壳2的谐振频率，因此扬声器模组3工作引发的气流冲击后壳2时，后壳2不容易振动。一种实施方式中，结构层5中的弹性缓冲结构52能够在压缩形变时产生压缩反弹力，使得结构层5向后壳2施加一个预紧力。在该预紧力的作用下，后壳2被支撑，因而不易在气流冲击下振动。因此在一体式连接和预紧力的共同作用下，后壳2的振动能被较好地抑制。
由于弹性缓冲结构52容易弹性形变，因此结构层5也具有弹性形变性能。当制造误差导致电池4与后壳2的间隙公差超过设计范围时，结构层5能够自适应形变以填充电池4与后壳2的间隙，保证电池4与后壳2能够可靠组装，即结构层5能起到适配电池4与后壳2的间隙公差的作用。特别的，当电池4为可以膨胀的软包电池4时，结构层5能够压缩以提供电池4膨胀所需的结构空间，避免电池4膨胀后将后壳2顶起，导致后壳2与壳体的间隙过大而造成整机外观缺陷。
常规方案是仅通过在后壳上仅粘贴泡棉来抑制壳振，但是抑制壳振的效果较差。在相同测试音源条件 下，使用普通泡棉的整机与本申请实施方式的电子设备对比。常规方案中后壳的振幅明显偏大，振幅可达8um-12um左右，表明后壳的振动较为强烈。相反，本申请实施方式的电子设备的后壳2的振幅最小可达2um-4um左右，改进后的振幅仅有常规方案的一半左右，表明后壳2的振幅得到明显抑制，用户体验表现为由明显麻手到几乎无振感。
一种实施方式中，本申请实施方式的结构层5为复合结构，不仅可以提供弹力还可以提供反约束力，并且设有能量耗散结构53来吸收消耗能量，因此本申请实施方式提供的结构层5的弹性大、阻尼因子大、约束力适中，可以有效地吸收振动。将各个结构组件做半约束处理以后，可以进一步的提升系统的刚度，提高产品的可靠性。
另外，出于电池4的安全、整机可靠性考虑，对结构层5与电池4连接提供的实际的力，要做到易剥离，保证电池4性能不受影响，因此通过设置结构层5两侧不同的连接强度，能够提升产品的可拆卸维护性。
综上所述，本申请实施方式既能够抑制后壳2振动，又能够满足产品组装需求、提升产品的可量产性及可拆卸维护性。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
